Abstract

The utility model discloses an oil & gas-fired hot water boiler, comprising a boiler shell, an internal furnace, a front tube sheet and a back tube sheet, a cylinder smoke pipe, a smoke pipe, a smoke box and a combustion machine. The front tube sheet and the back tube sheet are welded to the boiler shell and fixed on the foundation support. The boiler shell and the internal furnace are waist-circular cylinder shape and a waist-circular water jacket is formed at the empty cavity between them. The cylinder of smoke pipe is inclined and fixed in the internal furnace of the waist-circular cylinder, and the empty cavity of the cylinder of smoke pipe is isolated from the internal furnace and communicated with the water jacket of waist-circular cylinder. The smoke pipe is evenly distributed in the internal cavity of the cylinder of smoke pipe and inclined at the same inclination of the cylinder of smoke pipe, one end of the smoke pipe is communicated to the internal furnace, and the other end is located in the smoke box isolated from the water jacket of waist-circular cylinder. The utility model has the advantages of compact structure, large volume of the internal furnace and large heat radiation area, light weight, small occupied area, particularly suitable for small spaces.

Description

The fuel homogeneous solution-type reactor

Affiliated technical field

The utility model relates to a kind of fuel homogeneous solution-type reactor that is used to supply the domestic hot-water.

Background technology

At present, the middle-size and small-size horizontal fuel homogeneous solution-type reactor (30 * 10 of domestic each manufacturer's production and use ⁴-240 * 10 ⁴Kcal/h) mainly form by several major parts such as shell, flue, front and back tube sheet, smoke pipe, smoke box, combustors, shell, flue, smoke pipe and smoke box are welded on the tube sheet of front and back, combustor directly is fixed on the front smoke box plate, the thermal-flame that produces after the fuel combustion sprays into behind the burner hearth to return around the burner hearth and enters front smoke box, drains after single backhaul smoke pipe enters the back smoke box.This hot-water boiler is because flue is positioned at the body of heater center, and bottom smoke pipe heat exchange is poor, and utilization rate is low; Smoke pipe horizontal positioned, condensed water are difficult for draining and cause acid etching.Its main pressurized element structure all is circular in addition, and it is circular that the boiler profile also mostly is, and causes the boiler Heavy Weight, and floor space is big, often is subjected to the restriction of fabricating yard.

The utility model content

The purpose of this utility model is to provide a kind of energy-efficient, fuel homogeneous solution-type reactor that floor space is little.

The purpose of this utility model can realize by following technical measures: comprise shell, flue, the front and back tube sheet, the smoke pipe tube, smoke pipe, smoke box and combustor, front and back tube sheet and shell welding also are fixed on the underframe, it is characterized in that: described shell and flue are oval shape bar shape, cavity between shell and the flue is an oval shape water jacket, the smoke pipe tube tilts to be fixed in the oval shape flue, the inner chamber of smoke pipe tube and flue are isolated, communicate with oval shape water jacket, smoke pipe evenly branch is arranged in the smoke pipe tube inner chamber and has identical gradient with the smoke pipe tube, one port of smoke pipe communicates with flue, and a port of smoke pipe is arranged in the smoke box isolated with oval shape water jacket.

Be provided with deflector and several flexible stay bolts in the water jacket described in the utility model; Make current have higher rate of circulating flow and perturbation like this, can strengthen the heat convection of water in the water jacket.

Front and back described in the utility model tube sheet is the square tube sheet of external, and square front and back tube sheet is that movable bolt is connected with underframe; Body of heater can be to two ends free wxpansion like this.

The inclination angle of smoke pipe tube described in the utility model and smoke pipe is 3 ° to 4 °.

The utility model compared with prior art has following advantage: 1, compact conformation, flue volume and radiation heating-surface are long-pending big, the utility model can be to space and big capacity development than circular shell boiler under identical area occupied, in light weight with the utility model boiler under the capacity, be specially adapted to the place of small space; 2, oval type water jacket water capacity is little, and the even flexible stay bolt of many rows that distributes makes current have higher rate of circulating flow and perturbation in the water jacket, can strengthen the heat convection of water in the water jacket, and the hydrodynamic force operating mode obviously is better than circular shell boiler; The flexible stay bolt of many rows that evenly is welded on shell and the flue simultaneously can absorb shell, and flue is avoided distortion occurring, breaking because of the uneven thermal stress that is produced of being heated, thus the service life of improving boiler; 3, hang tilting smoke pipe tube and make the furnace high-temperature flue gas, can strengthen radiation and the shining heat of convection current in the stove along its high speed rotation disturbance; And the tilting threaded flue is convenient to discharging of flue gas condensing water and deashing in the smoke pipe.

Description of drawings

Fig. 1 is the structural representation of the utility model fuel homogeneous solution-type reactor.

Fig. 2 is that A among Fig. 1 is to view.

The specific embodiment

As shown in Figure 1 and Figure 2, comprise shell 4, flue 6, front and back tube sheet 3,11, smoke pipe tube 7, smoke pipe 9, smoke box 12 and combustor 1, front and back tube sheet 3,11 is the square tube sheet of external, and square front and back tube sheet is that movable bolt is connected with underframe; Body of heater can be to two ends free wxpansion like this.Shell 4 and flue 6 are oval shape bar shape, and the cavity between shell and the flue is an oval shape water jacket, are provided with deflector 13 and several flexible stay bolts 15 in the water jacket; Feed pipe 14 is positioned at the shell rear lower, feedwater enters in oval shape water jacket and the smoke pipe tube 7 through deflector 13 shuntings, the flexible stay bolt 15 of many rows is except that strengthening shell, flue, also make the abundant disturbance of feedwater, make current have higher rate of circulating flow and perturbation, can strengthen the heat convection of water in the water jacket, heated hot water is confessed through outlet pipe 5.Smoke pipe letter 7 tilts to be fixed in the oval shape flue 6, the inclination angle of smoke pipe tube is 4 °, and the inner chamber of smoke pipe tube and flue are isolated, communicate with oval shape water jacket, smoke pipe 9 evenly branch is arranged in the smoke pipe tube inner chamber and has identical gradient with the smoke pipe tube, is convenient to discharging of flue gas condensing water and deashing in the smoke pipe.One port of smoke pipe 9 communicates with flue 6, and a port of smoke pipe 9 is arranged in the smoke box 12 isolated with oval shape water jacket.Fuel vapor sprays into oval type flue 6 burning and radiation heat transfers through combustor 1, fully the high-temperature flue gas after the burning is along the rotation at a high speed of smoke pipe tube 7 surfaces, and enter threaded flue 9 from the front portion, and behind heat convection, entering smoke box 12 and from chimney, enter atmosphere, whole flue gas flow is the type of falling an e track.

The utility model can be provided with automatic controller; realize the automatic adjusting of burning, automatic water supplement, automatic temperature-control, regularly startup, fault alarm, fault diagnosis, superpressure, overtemperature, lack of water and multiple protective such as flame-out; centralized Control and building communication interface function can be provided, make boiler be in operation under the optimal economic state.
